L8A is the supply for UFS VCC, UFS specification allows different VCC
configurations for UFS devices.
-UFS 2.x devices: 2.70V - 3.60V
-UFS 3.x devices: 2.40V - 2.70V
As sa8775p-ride supports both ufs 2.x and ufs 3.x devices, remove min/max
voltages for L8A regulator. Initial voltage of L8A will be set to 2.504v
or 2.952v during PON depending on the UFS device type. On sa8775, UFS is
the only client in Linux for L8A and this regulator will be voted only
for enabling/disabling.
